Lyle Jeffs, the indicted leader of the polygamist sect Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS), likely used olive oil to slip off his GPS ankle monitor while under house arrest, according to The Associated Press. The FLDS bishop had been released from jail in June after his trial over food-stamp fraud had been delayed.

Jeffs was arrested alongside 10 other church leaders last year for the multi-million dollar scheme, though the rest of those indicted had not only been released early but had complied to the court’s conditions, AP reports. Jeffs continued to handle day-to-day operations in the community from jail. Within two weeks of his early release, he had removed his monitor, and the FBI is speculating that olive oil had been the reason why. A Ford Mustang had been spotted outside of his home the same June weekend that he had escaped and may also be the car he had driven off in. The FBI has declared Jeffs “armed and dangerous” on their official wanted poster for the leader.

Jeffs is the brother of currently imprisoned FLDS “prophet” Warren Jeffs. He was sentenced to life in prison in 2011 for rapping a child. Soon after, the church and Lyle and were posed with legal troubles surrounding their child-labor conditions before the food-stamp scheme put them in deeper debt.

The FLDS church, which is based primarily in Utah and Arizona, is not affiliated with the Church of Jesus Christ of Latter-Day Saints (LDS), the more mainstream Mormon church. The FLDS is known best for their practice of polygamy, something that the LDS church has staunchly separated itself from.
